Stevia supplier PureCircle has received a notice of allowance from the US Patent and Trademark Office for the production of high purity stevia sweeteners.

The UK-listed firm earlier this month launched a global campaign in a bid to boost awareness of the natural sweetener among consumers.

Issuance of the US patent, the company said today (31 August), will provide it with “strong competitive advantage and protections” across PureCircle’s portfolio of high purity stevia products.

The patent is expected to expire in 2025.

PureCircle has around 49 additional patent applications in various stages in the review process, submitted across global markets, which would further establish barriers to entry in the stevia industry.

Magomet Malsagov, CEO and managing director of PureCircle said: “This patent underscores the strength of our R&D and operations teams as pioneers within the stevia industry.”
